Subject: [PATCH] pstore/ram: Register to module device table
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Register the compatible for this module on the module device table so
it can be automatically loaded when a matching DT node is present,
allowing logging of panics and oopses without any intervention.
